[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise expressly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise expressly specified and limited, the first feature being "above" or "below" the second feature may include direct contact between the first and second features, or contact between the first and second features not being in direct contact but through another feature between them.

[0031] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] This embodiment provides a connection structure, combined with Figure 1 , Figure 2 As shown, the connecting mechanism includes a rotating base 1, a first connecting component 2, a second connecting component 3, a locking component 4, and an unlocking component 5.

[0033] like Figure 2 As shown, the rotating base 1 has a cylindrical structure, and a connecting through hole 11 is provided on the rotating base 1 along the first direction X1, where the first direction X1 is parallel to the center line of the rotating base 1. It can be understood that the cross-section of the connecting through hole 11 is circular, that is, the connecting through hole 11 is a circular through hole.

[0034] Combination Figure 1 , Figure 2 As shown, one end of the first connecting component 2 can be inserted into the connecting through hole 11 on the rotating base 1. When the rotating base 1 rotates relative to the first connecting component 2 about a center line parallel to the first direction X1 to a first preset position, it can restrict the movement of the first connecting component 2 in the first direction X1; when the rotating base 1 rotates relative to the first connecting component 2 about a center line parallel to the first direction X1 to a second preset position, it can release the movement restriction of the first connecting component 2 in the first direction X1. It is easy to understand that the second preset position here can be the initial position when the rotating base 1 rotates, or it can be a position other than the initial position and the first preset position after the rotating base 1 has rotated from the first preset position in other directions. The first connecting component 2 is used to connect a first device, such as a drone, specifically as follows: Figure 1 As shown, a plurality of connecting arms 23 are provided circumferentially on the outer side wall of the first connecting assembly 2 away from the rotating seat 1. The connecting arms 23 are used for detachable connection with the first device. The detachable connection between the two is achieved by means of bolt connection or snap-fit.

[0035] The second connecting component 3 is detachably connected to the rotating base 1. This second connecting component 3 is used to connect a second device, specifically as follows: Figure 2 As shown, the second connecting assembly 3 includes a connecting seat 45 detachably connected to the rotating base 1. The connecting seat 45 is used for detachable connection to a second device, such as a load-bearing device. The connection between the connecting seat 45 and the rotating base 1, and between the connecting seat 45 and the second device, is, for example, by bolt connection or snap-fit.

[0036] When the rotating seat 1 is in the first preset position, the locking assembly 4 can restrict the rotating seat 1 from rotating around a center line parallel to the first direction X1. In addition, when the rotating seat 1 is in the first preset position, the locking assembly 4 can be unlocked from the rotating seat 1 by means of the unlocking assembly 5.

[0037] Therefore, the connecting mechanism provided in this embodiment includes a rotating seat 1 with a connecting through hole 11 along the first direction X1, a first connecting component 2 with one end capable of being inserted into the connecting through hole 11, and a second connecting component 3 detachably connected to the rotating seat 1. When the rotating seat 1 rotates relative to the first connecting component 2 around a center line parallel to the first direction X1 to a first preset position, it can restrict the movement of the first connecting component 2 in the first direction X1, that is, restrict the positions of the first connecting component 2 and the second connecting component 3 in the first direction X1. When the rotating seat 1 rotates relative to the first connecting component 2 around a center line parallel to the first direction X1 to a second preset position, it can release the movement restriction of the first connecting component 2 in the first direction X1, that is, release the position restriction of the first connecting component 2 and the second connecting component 3 in the first direction X1. This allows the first connecting component 2 and the second connecting component 3 to be installed or removed by rotating the rotating seat 1, making the installation and removal process quick and convenient. Furthermore, a locking assembly 4 is provided. When the rotating seat 1 rotates around the first direction X1 to the first preset position, the locking assembly 4 can restrict the rotation of the rotating seat 1 around the first direction X1, preventing the first connecting component 2 from becoming loose from the rotating seat 1, thereby ensuring the stability of the connection between the first connecting component 2 and the second connecting component 3. In addition, an unlocking assembly 5 is provided. When the rotating seat 1 rotates around the first direction X1 to the first preset position, the unlocking assembly 5 can unlock the locking assembly 4 and the rotating seat 1. This allows the locking assembly 4 to improve the stability of the connection between the first connecting component 2 and the second connecting component 3 during the above-mentioned operation, thereby improving the safety of the operation. At the same time, the unlocking assembly 5 can be used to unlock the first connecting component 2 and the second connecting component 3 during disassembly, thereby improving the convenience of disassembly.

[0038] In some embodiments, such as Figure 2 As shown, the aforementioned rotating base 1 has a locking through hole 12 communicating with the connecting through hole 11 along the second direction X2. Specifically, the locking through hole 12 is opened on the outer side wall of the rotating base 1, and the center line of the locking through hole 12 is perpendicular to the center line of the connecting through hole 11 (that is, perpendicular to the first direction X1). The aforementioned second direction X2 is set at an angle to the first direction X1, for example, 90°.

[0039] like Figure 2As shown, the locking assembly 4 includes a locking seat 41 and a locking component 42. The locking component 42 is disposed on the outer wall of the locking seat 41 and is movable along the second direction X2. The locking seat 41 is rotatably disposed inside the connecting through hole 11. The rotatable connection between the two is achieved, for example, by a clearance fit between the outer wall of the locking seat 41 and the inner wall of the connecting through hole 11. When the locking component 42 is inserted into the locking through hole 12, it restricts the rotation of the rotating seat 1 around a centerline parallel to the first direction X1, thereby locking the position of the rotating seat 1.

[0040] For example, such as Figure 2 As shown, a mounting hole 43 is provided on the outer wall of the locking seat 41, and the locking assembly 42 is disposed within the mounting hole 43. The locking assembly 42 includes a locking member 421 and a first elastic member 422. The locking member 421 is, for example, a cylindrical rod-shaped structure, and the first elastic member 422 is, for example, a spring or a rubber column. The first elastic member 422 is disposed between the locking member 421 and the bottom of the mounting hole 43, and the first elastic member 422 always has a tendency to push the locking member 421 away from the locking seat 41. In other words, the first elastic member 422 always has a tendency to push the locking member 421 away from the locking seat 41.

[0041] The aforementioned unlocking component 5 is disposed on the outer side wall of the rotating base 1. When the unlocking component 5 moves close to the locking base 41 along the second direction X2, it can push the locking component 42 out of the locking through hole 12 opened on the rotating base 1, thereby unlocking the locking base 41 from the rotating base 1.

[0042] For example, such as Figure 2 As shown, the unlocking assembly 5 includes an actuating element 51, a fixed base 52, and a second elastic element 53. The second elastic element 53 is located between the outer walls of the fixed base 52 and the rotating base 1. The actuating element 51 passes through the fixed base 52 and abuts against the second elastic element 53, while the second elastic element 53 always tends to push the actuating element 51 away from the rotating base 1. Specifically, the fixed base 52 has an opening for the actuating element 51 to pass through, and a first protrusion 521 restricting the movement of the actuating element 51 in the second direction X2 is provided at this opening. A second protrusion 512 is provided on the outer wall of the actuating element 51 near the rotating base 1. When the actuating element 51 moves away from the rotating base 1 under the elastic force of the second elastic element 53, the first protrusion 521 on the fixed base 52 abuts against the second protrusion 512 on the actuating element 51, thereby limiting the actuating element 51 and preventing it from detaching from the fixed base 52 under the elastic force of the second elastic element 53. Specifically Figure 2Taking the perspective shown as an example, when the above-mentioned connecting mechanism is actually assembled, the second protruding part 512 of the actuating member 51 is located on the right side of the first protruding part 521 of the fixed seat 52 (that is, located between the first protruding part 521 and the rotating seat 1). When the actuating member 51 moves to the left under the elastic force of the second elastic member 53, the left side of the second protruding part 512 abuts against the right side of the first protruding part 521, thereby restricting the movement of the actuating member 51 in the second direction X2.

[0043] To facilitate unlocking of the locking component 42, the aforementioned actuating element 51 is further provided with an unlocking part 511, which is directly opposite to the aforementioned locking through hole 12. Here, "directly opposite" means that the center line of the unlocking part 511 coincides with the center line of the locking through hole 12. It is also easy to understand that the unlocking part 511 should be adapted to the locking through hole 12. For example, when the aforementioned locking through hole 12 is a circular through hole, the unlocking part 511 has a cylindrical elongated structure, and the outer diameter of the unlocking part 511 is the same as or slightly smaller than the inner diameter of the locking through hole 12, thereby ensuring that the unlocking part 511 can move smoothly within the locking through hole 12.

[0044] When the connecting mechanism needs to be locked, the actuating member 51 disengages from the locking through hole 12 under the elastic force of the second elastic member 53, while the locking member 421 is inserted into the locking through hole 12 under the elastic force of the first elastic member 422, thus achieving locking. When the connecting mechanism needs to be unlocked, the operator pushes the actuating member 51 towards the rotating seat 1 against the elastic force of the second elastic member 53. The unlocking part 511 provided on the actuating member 51 is inserted into the locking through hole 12 and abuts against the locking member 421 located in the locking through hole 12, causing the locking member 421 to move away from the locking through hole 12 against the elastic force of the first elastic member 422 until the locking member 421 disengages from the locking through hole 12, thus achieving unlocking.

[0045] In the above-described connecting mechanism, by providing a locking through hole 12 on the rotating base 1, the locking assembly 4 is configured as a locking base 41 and a locking component 42 disposed in a mounting hole 43 on the outer side wall of the locking base 41. The unlocking component 5 is disposed on the outer side wall of the rotating base 1. Furthermore, the locking component 42 is configured as a locking member 421 and a first elastic member 422 disposed between the locking member 421 and the bottom of the mounting hole 43. The unlocking component 5 is configured as an actuating member 51 with an unlocking part 511, a fixing base 52, and a second elastic member 53 disposed between the actuating member 51 and the outer side wall of the rotating base 1. This ensures that when the above-described connecting mechanism needs to be locked... Under the elastic force of the second elastic member 53, the actuating member 51 can disengage from the locking through hole 12, while the locking member 421 can insert into the locking through hole 12 under the elastic force of the first elastic member 422, thus achieving locking. When the above-mentioned connecting mechanism needs to be unlocked, the operator pushes the actuating member 51 towards the rotating seat 1 against the elastic force of the second elastic member 53. The unlocking part 511 provided on the actuating member 51 can be inserted into the locking through hole 12 and abut against the locking member 421 located in the locking through hole 12, causing the locking member 421 to move away from the locking through hole 12 against the elastic force of the first elastic member 422 until the locking member 421 disengages from the locking through hole 12, thus achieving unlocking. The structure is simple, easy to design and manufacture, easy to install and use, and improves the practicality of the connecting mechanism.

[0046] In some embodiments, such as Figure 2 As shown, a limiting block 21 is provided on the outer wall of the end of the first connecting component 2 that is inserted into the connecting through hole 11, and a limiting flange 111 is provided at the opening of the connecting through hole 11 away from the second connecting component 3. For example, the limiting block 21 is an elongated block structure that extends circumferentially along the outer wall of the first connecting component 2. Alternatively, it can be understood that the limiting block 21 is an arc-shaped block structure with the same curvature as the outer wall of the first connecting component 2. Similarly, the limiting flange 111 has a similar structure to the limiting block 21, also being an elongated block structure (arc-shaped block structure), which will not be described again here.

[0047] When the aforementioned rotating seat 1 is in the first preset position, in the first direction X1, the limiting block 21 cooperates with the limiting flange 111 to restrict the movement of the first connecting assembly 2 in the first direction X1. Specifically, as shown... Figure 2Taking the perspective shown as an example, after inserting the first connecting component 2 into the connecting through hole 11 of the rotating seat 1 and rotating the rotating seat 1 to the first preset position, the limiting block 21 will be located directly below the limiting flange 111. At this time, if the first connecting component 2 moves away from the connecting through hole 11 (moves upward), the upper surface of the limiting block 21 will abut against the lower surface of the limiting flange 111, thereby restricting the movement of the first connecting component 2 in the first direction X1.

[0048] In the above-mentioned connecting mechanism, a limiting block 21 is provided on the outer wall of one end of the first connecting component 2 inserted into the connecting through hole 11, and a limiting flange 111 is provided at the opening of the connecting through hole 11 away from the second connecting component 3. This allows the first connecting component 2 to be restricted from moving in the first direction X1 by the cooperation of the limiting block 21 and the limiting flange 111 when the rotating seat 1 rotates to the first preset position. The structure is simple, easy to use, and easy to manufacture.

[0049] It is easy to understand that the number of the aforementioned limiting block 21 and limiting flange 111 can be one or more. When there is one limiting block 21 and one limiting flange 111, the length of the limiting block 21 should be less than or equal to 1 / 2 the circumferential length of the outer sidewall of the first connecting component 2. Similarly, the length of the limiting flange 111 should be less than or equal to 1 / 2 the circumferential length of the inner sidewall of the connecting through hole 11. At the same time, the length of the limiting block 21 should be matched with the length of the limiting flange 111 to ensure that the first connecting component 2 can be smoothly inserted into the connecting through hole 11.

[0050] When there are multiple limiting blocks 21 and multiple limiting flanges 111, for example, such as Figure 2As shown, multiple limiting blocks 21 are arranged circumferentially along the outer side wall of the first connecting assembly 2. For example, there are three limiting blocks 21, and adjacent limiting blocks 21 are arranged at an included angle of 120°. Furthermore, the orthographic projections of adjacent limiting blocks 21 on the locking assembly 4 are different in size; in other words, the circumferential dimensions of adjacent limiting blocks 21 on the outer side wall of the first connecting assembly 2 are different. Multiple limiting flanges 111 are arranged circumferentially along the opening of the connecting through hole 11. For example, the number of limiting flanges 111 is equal to the number of limiting blocks 21, that is, there are also three limiting flanges 111, and adjacent limiting flanges 111 are arranged at an included angle of 120°. There are insertion notches between adjacent limiting flanges 111, and the multiple insertion notches are respectively adapted to the multiple limiting blocks 21, ensuring that the first connecting assembly 2 can be smoothly machined into the connecting through hole 11 through the insertion notches. By setting the number of limiting blocks 21 and limiting flanges 111 to multiple, the stability of the connection between the first connecting component 2 and the connecting through hole 11 on the rotating seat 1 can be improved. By setting the shapes of two adjacent limiting blocks 21 to be different and setting the insertion notch between two adjacent limiting flanges 111 to be adapted to the limiting blocks 21, it can be ensured that the first connecting component 2 can only be inserted into the connecting through hole 11 at a specific angle, realizing the "foolproof" design and improving the practicality of the connecting mechanism.

[0051] In some embodiments, such as Figure 2 As shown, the aforementioned limiting block 21 is provided with a first guide surface 211, and the aforementioned limiting flange 111 is provided with a second guide surface 1111. When the aforementioned rotating seat 1 rotates from the second preset position to the first preset position, the first guide surface 211 and the second guide surface 1111 cooperate to achieve a guiding function. Specifically, with Figure 2 Taking the shown perspective as an example, the first guide surface 211 is disposed on the upper surface of the limiting block 21, and the second guide surface 1111 is disposed on the lower surface of the limiting flange 111. Taking the rotation of the rotating seat 1 from the second preset position to the first preset position as a counterclockwise rotation as an example, the first guide surface 211 is disposed on the left half of the limiting block 21 and is inclined from the lower left to the upper right. The second guide surface 1111 is disposed on the right half of the limiting flange 111 and is inclined in the same direction as the first guide surface 211. If taking the rotation of the rotating seat 1 from the second preset position to the first preset position as a clockwise rotation as an example, the first guide surface 211 is disposed on the right half of the limiting block 21 and is inclined from the lower right to the upper left. The second guide surface 1111 is disposed on the left half of the limiting flange 111 and is inclined in the same direction as the first guide surface 211. Those skilled in the art can flexibly set the positions of the first guide surface 211 and the second guide surface 1111 according to actual usage requirements, without making too many limitations here.

[0052] In some embodiments, such as Figure 3As shown, the end face of the first connecting component 2 inserted into the connecting through hole 11 is provided with at least one positioning hole 22, and the locking seat 41 of the locking assembly 4 is provided with at least one positioning post 44 on the side near the first connecting component 2, the positioning post 44 being adapted to the positioning hole 22. For example, the end face of the first connecting component 2 inserted into the connecting through hole 11 is provided with two positioning holes 22, and correspondingly, the locking seat 41 is provided with two positioning posts 44 on the side near the first connecting component 2. The positioning post 44 has a cylindrical structure, the positioning hole 22 is a circular blind hole, the center line of the positioning post 44 coincides with the center line of the positioning hole 22, the outer diameter of the positioning post 44 is the same as the inner diameter of the positioning hole 22, and in the first direction X1, the size of the positioning post 44 is the same as the size of the positioning hole 22, that is, the height of the positioning post 44 is the same as the depth of the positioning hole 22. It is easy to understand that the shape of the positioning post 44 is not limited to a cylindrical structure, but can also be a prism structure, such as a triangular prism or a quadrangular prism. Therefore, the opening shape of the positioning hole 22 can also be a triangle or a square. In addition, the positions of the positioning post 44 and the positioning hole 22 can also be interchanged. That is, the positioning post 44 is provided on the locking seat 41, and the positioning hole 22 is provided on the first connecting component 2. Those skilled in the art can make adaptive settings according to actual needs, and no further limitations are made here.

[0053] In the above-mentioned connecting mechanism, by providing a positioning hole 22 on the first connecting component 2 and a positioning pin 44 on the locking seat 41 of the locking component 4, the positioning pin 44 and the positioning hole 22 can cooperate to play a positioning role after the first connecting component 2 is inserted into the connecting through hole 11 of the rotating seat 1, thus preventing the first connecting component 2 from rotating around the center line parallel to the first direction X1, making the first connecting component 2 more firmly connected; in addition, during the process of the first connecting component 2 being inserted into the connecting through hole 11 of the rotating seat 1, the cooperation between the positioning pin 44 and the positioning hole 22 can further play a foolproof role, improving the practicality of the connecting mechanism.

[0054] In some embodiments, combined with Figure 4 , Figure 2As shown, a limiting notch 112 is provided at the opening of the connecting through hole 11 near the second connecting component 3. The outer wall of the locking seat 41 is provided with a limiting part 13 that can be inserted into the limiting notch 112. The limiting part 13 cooperates with the limiting notch 112 to restrict the rotating seat 1 to rotate only between the first preset position and the second preset position. Specifically, the limiting notch 112 is an arc-shaped notch, and in the circumferential direction of the rotating seat 1, the length of the limiting notch 112 is the same as the distance between the first preset position and the second preset position. The limiting part 13 has a block-shaped protrusion structure. When the rotating seat 1 is in the first preset position, the limiting part 13 abuts against one end of the limiting notch 112. When the rotating seat 1 is in the second preset position, the limiting part 13 abuts against the other end of the limiting notch 112. By setting it in this way, the limiting part 13 is restricted to the limiting notch 112 and can only move within the length range of the limiting notch 112. This also means that the rotating seat 1 can only rotate between the first preset position and the second preset position, avoiding the operator's mistake that the rotating seat 1 rotates too much, causing the rotating seat 1 to fail to restrict the first connecting component 2 in the first direction X1, thus improving the reliability of the connecting mechanism during use.

[0055] In some embodiments, such as Figure 2 As shown, the end face of the first connecting component 2 inserted into the connecting through hole 11 is provided with a coupling interface 24. At the same time, the rotating seat 1 is provided with a coupling plug 14 on the side close to the first connecting component 2. When the coupling plug 14 is inserted into the coupling interface 24, the coupling between the first device connected to the first connecting component 2 and the second device connected to the second connecting component 3 can be realized. With this arrangement, data transmission or current transmission between different devices can be realized, which improves the applicability of the connecting mechanism.

[0056] In some embodiments, the first connecting component 2 has a reference mark on its outer wall outside the connecting through hole 11, and the rotating seat 1 has locking and unlocking marks spaced circumferentially on its outer wall. The reference mark, locking mark, and unlocking mark can be color-coded dots, raised marks, or recessed marks. When the rotating seat 1 is in a first preset position, the locking mark is aligned with the reference mark in the first direction X1; when the rotating seat 1 is in a second preset position, the unlocking mark is aligned with the reference mark in the first direction X1. This configuration allows operators to clearly and intuitively observe the working status of the connecting mechanism (i.e., whether it is in a locked or unlocked state), providing visual guidance, preventing operator misoperation, and improving the practicality of the connecting mechanism.

[0057] In some embodiments, such as ​As shown, the aforementioned connection mechanism also includes a protective cover 6 fastened to the first connection component 2. The outer wall of the protective cover 6 has a wiring hole 61 for the wire harness to pass through, and the opening of the wiring hole 61 is sealed with a waterproof sealant 62. This design allows the protective cover 6 to protect the internal electrical or mechanical structures of the first connection component 2, preventing debris or liquids from entering the first connection component 2 and affecting the stability of the connection between the first and second devices, thus improving the adaptability of the connection mechanism to different environments.
